Why your organization should consider an MDR solution and five key things to look for in a service offering
The post Understanding Managed Detection and Response – and what to look for in an MDR solution appeared first on WeLiveSecurity
Google says it has suspended the app for the Chinese e-commerce giant Pinduoduo after malware was found in versions of the software. The move comes just weeks after Chinese security researchers published an analysis suggesting the popular e-commerce app sought to seize total control over affected devices by exploiting multiple security vulnerabilities in a variety of Android-based smartphones.
In November 2022, researchers at Google’s Project Zero warned about active attacks on Samsung mobile phones which chained together three security vulnerabilities that Samsung patched in March 2021, and which would have allowed an app to add or read any files on the device.
Google said it believes the exploit chain for Samsung devices belonged to a “commercial surveillance vendor,” without elaborating further. The highly technical writeup also did not name the malicious app in question.
On Feb. 28, 2023, researchers at the Chinese security firm DarkNavy published a blog post purporting to show evidence that a major Chinese ecommerce company’s app was using this same three-exploit chain to read user data stored by other apps on the affected device, and to make its app nearly impossible to remove.
DarkNavy likewise did not name the app they said was responsible for the attacks. In fact, the researchers took care to redact the name of the app from multiple code screenshots published in their writeup. DarkNavy did not respond to requests for clarification.
“At present, a large number of end users have complained on multiple social platforms,” reads a translated version of the DarkNavy blog post. “The app has problems such as inexplicable installation, privacy leakage, and inability to uninstall.”
Update, March 27, 1:24 p.m. ET: Dan Goodin over at Ars Technica has an important update on this story that indicates the Pinduoduo code was exploiting a zero-day vulnerability in Android — not Samsung. From that piece:
“A preliminary analysis by Lookout found that at least two off-Play versions of Pinduoduo for Android exploited CVE-2023-20963, the tracking number for an Android vulnerability Google patched in updates that became available to end users two weeks ago. This privilege-escalation flaw, which was exploited prior to Google’s disclosure, allowed the app to perform operations with elevated privileges. The app used these privileges to download code from a developer-designated site and run it within a privileged environment.
“The malicious apps represent “a very sophisticated attack for an app-based malware,” Christoph Hebeisen, one of three Lookout researchers who analyzed the file, wrote in an email. “In recent years, exploits have not usually been seen in the context of mass-distributed apps. Given the extremely intrusive nature of such sophisticated app-based malware, this is an important threat mobile users need to protect against.”
On March 3, 2023, a denizen of the now-defunct cybercrime community BreachForums posted a thread which noted that a unique component of the malicious app code highlighted by DarkNavy also was found in the ecommerce application whose name was apparently redacted from the DarkNavy analysis: Pinduoduo.
A Mar. 3, 2023 post on BreachForums, comparing the redacted code from the DarkNavy analysis with the same function in the Pinduoduo app available for download at the time.
On March 4, 2023, e-commerce expert Liu Huafang posted on the Chinese social media network Weibo that Pinduoduo’s app was using security vulnerabilities to gain market share by stealing user data from its competitors. That Weibo post has since been deleted.
On March 7, the newly created Github account Davinci1010 published a technical analysis claiming that until recently Pinduoduo’s source code included a “backdoor,” a hacking term used to describe code that allows an adversary to remotely and secretly connect to a compromised system at will.
That analysis includes links to archived versions of Pinduoduo’s app released before March 5 (version 6.50 and lower), which is when Davinci1010 says a new version of the app removed the malicious code.
Pinduoduo has not yet responded to requests for comment. Pinduoduo parent company PDD Holdings told Reuters Google has not shared details about why it suspended the app.
The company told CNN that it strongly rejects “the speculation and accusation that Pinduoduo app is malicious just from a generic and non-conclusive response from Google,” and said there were “several apps that have been suspended from Google Play at the same time.”
Pinduoduo is among China’s most popular e-commerce platforms, boasting approximately 900 million monthly active users.
Most of the news coverage of Google’s move against Pinduoduo emphasizes that the malware was found in versions of the Pinduoduo app available outside of Google’s app store — Google Play.
“Off-Play versions of this app that have been found to contain malware have been enforced on via Google Play Protect,” a Google spokesperson said in a statement to Reuters, adding that the Play version of the app has been suspended for security concerns.
However, Google Play is not available to consumers in China. As a result, the app will still be available via other mobile app stores catering to the Chinese market — including those operated by Huawei, Oppo, Tencent and VIVO.
Google said its ban did not affect the PDD Holdings app Temu, which is an online shopping platform in the United States. According to The Washington Post, four of the Apple App Store’s 10 most-downloaded free apps are owned by Chinese companies, including Temu and the social media network TikTok.
The Pinduoduo suspension comes as lawmakers in Congress this week are gearing up to grill the CEO of TikTok over national security concerns. TikTok, which is owned by Beijing-based ByteDance, said last month that it now has roughly 150 million monthly active users in the United States.
A new cybersecurity strategy released earlier this month by the Biden administration singled out China as the greatest cyber threat to the U.S. and Western interests. The strategy says China now presents the “broadest, most active, and most persistent threat to both government and private sector networks,” and says China is “the only country with both the intent to reshape the international order and, increasingly, the economic, diplomatic, military, and technological power to do so.”
A new breach involving data from nine million AT&T customers is a fresh reminder that your mobile provider likely collects and shares a great deal of information about where you go and what you do with your mobile device — unless and until you affirmatively opt out of this data collection. Here’s a primer on why you might want to do that, and how.

Telecommunications giant AT&T disclosed this month that a breach at a marketing vendor exposed certain account information for nine million customers. AT&T said the data exposed did not include sensitive information, such as credit card or Social Security numbers, or account passwords, but was limited to “Customer Proprietary Network Information” (CPNI), such as the number of lines on an account.
Certain questions may be coming to mind right now, like “What the heck is CPNI?” And, ‘If it’s so ‘customer proprietary,’ why is AT&T sharing it with marketers?” Also maybe, “What can I do about it?” Read on for answers to all three questions.
AT&T’s disclosure said the information exposed included customer first name, wireless account number, wireless phone number and email address. In addition, a small percentage of customer records also exposed the rate plan name, past due amounts, monthly payment amounts and minutes used.
CPNI refers to customer-specific “metadata” about the account and account usage, and may include:
-Called phone numbers
-Time of calls
-Length of calls
-Cost and billing of calls
-Service features
-Premium services, such as directory call assistance
According to a succinct CPNI explainer at TechTarget, CPNI is private and protected information that cannot be used for advertising or marketing directly.
“An individual’s CPNI can be shared with other telecommunications providers for network operating reasons,” wrote TechTarget’s Gavin Wright. “So, when the individual first signs up for phone service, this information is automatically shared by the phone provider to partner companies.”
Is your mobile Internet usage covered by CPNI laws? That’s less clear, as the CPNI rules were established before mobile phones and wireless Internet access were common. TechTarget’s CPNI primer explains:
“Under current U.S. law, cellphone use is only protected as CPNI when it is being used as a telephone. During this time, the company is acting as a telecommunications provider requiring CPNI rules. Internet use, websites visited, search history or apps used are not protected CPNI because the company is acting as an information services provider not subject to these laws.”
Hence, the carriers can share and sell this data because they’re not explicitly prohibited from doing so. All three major carriers say they take steps to anonymize the customer data they share, but researchers have shown it is not terribly difficult to de-anonymize supposedly anonymous web-browsing data.
“Your phone, and consequently your mobile provider, know a lot about you,” wrote Jack Morse for Mashable. “The places you go, apps you use, and the websites you visit potentially reveal all kinds of private information — e.g. religious beliefs, health conditions, travel plans, income level, and specific tastes in pornography. This should bother you.”
Happily, all of the U.S. carriers are required to offer customers ways to opt out of having data about how they use their devices shared with marketers. Here’s a look at some of the carrier-specific practices and opt-out options.
AT&T’s policy says it shares device or “ad ID”, combined with demographics including age range, gender, and ZIP code information with third parties which explicitly include advertisers, programmers, and networks, social media networks, analytics firms, ad networks and other similar companies that are involved in creating and delivering advertisements.
AT&T said the data exposed on 9 million customers was several years old, and mostly related to device upgrade eligibility. This may sound like the data went to just one of its partners who experienced a breach, but in all likelihood it also went to hundreds of AT&T’s partners.
AT&T’s CPNI opt-out page says it shares CPNI data with several of its affiliates, including WarnerMedia, DirecTV and Cricket Wireless. Until recently, AT&T also shared CPNI data with Xandr, whose privacy policy in turn explains that it shares data with hundreds of other advertising firms. Microsoft bought Xandr from AT&T last year.
According to the Electronic Privacy Information Center (EPIC), T-Mobile seems to be the only company out of the big three to extend to all customers the rights conferred by the California Consumer Privacy Act (CCPA).
EPIC says T-Mobile customer data sold to third parties uses another unique identifier called mobile advertising IDs or “MAIDs.” T-Mobile claims that MAIDs don’t directly identify consumers, but under the CCPA MAIDs are considered “personal information” that can be connected to IP addresses, mobile apps installed or used with the device, any video or content viewing information, and device activity and attributes.
T-Mobile customers can opt out by logging into their account and navigating to the profile page, then to “Privacy and Notifications.” From there, toggle off the options for “Use my data for analytics and reporting” and “Use my data to make ads more relevant to me.”
Verizon’s privacy policy says it does not sell information that personally identities customers (e.g., name, telephone number or email address), but it does allow third-party advertising companies to collect information about activity on Verizon websites and in Verizon apps, through MAIDs, pixels, web beacons and social network plugins.
According to Wired.com’s tutorial, Verizon users can opt out by logging into their Verizon account through a web browser or the My Verizon mobile app. From there, select the Account tab, then click Account Settings and Privacy Settings on the web. For the mobile app, click the gear icon in the upper right corner and then Manage Privacy Settings.
On the privacy preferences page, web users can choose “Don’t use” under the Custom Experience section. On the My Verizon app, toggle any green sliders to the left.
EPIC notes that all three major carriers say resetting the consumer’s device ID and/or clearing cookies in the browser will similarly reset any opt-out preferences (i.e., the customer will need to opt out again), and that blocking cookies by default may also block the opt-out cookie from being set.
T-Mobile says its opt out is device-specific and/or browser-specific. “In most cases, your opt-out choice will apply only to the specific device or browser on which it was made. You may need to separately opt out from your other devices and browsers.”
Both AT&T and Verizon offer opt-in programs that gather and share far more information, including device location, the phone numbers you call, and which sites you visit using your mobile and/or home Internet connection. AT&T calls this their Enhanced Relevant Advertising Program; Verizon’s is called Custom Experience Plus.
In 2021, multiple media outlets reported that some Verizon customers were being automatically enrolled in Custom Experience Plus — even after those customers had already opted out of the same program under its previous name — “Verizon Selects.”
If none of the above opt out options work for you, at a minimum you should be able to opt out of CPNI sharing by calling your carrier, or by visiting one of their stores.
Why should you opt out of sharing CPNI data? For starters, some of the nation’s largest wireless carriers don’t have a great track record in terms of protecting the sensitive information that you give them solely for the purposes of becoming a customer — let alone the information they collect about your use of their services after that point.
In January 2023, T-Mobile disclosed that someone stole data on 37 million customer accounts, including customer name, billing address, email, phone number, date of birth, T-Mobile account number and plan details. In August 2021, T-Mobile acknowledged that hackers made off with the names, dates of birth, Social Security numbers and driver’s license/ID information on more than 40 million current, former or prospective customers who applied for credit with the company.
Last summer, a cybercriminal began selling the names, email addresses, phone numbers, SSNs and dates of birth on 23 million Americans. An exhaustive analysis of the data strongly suggested it all belonged to customers of one AT&T company or another. AT&T stopped short of saying the data wasn’t theirs, but said the records did not appear to have come from its systems and may be tied to a previous data incident at another company.
However frequently the carriers may alert consumers about CPNI breaches, it’s probably nowhere near often enough. Currently, the carriers are required to report a consumer CPNI breach only in cases “when a person, without authorization or exceeding authorization, has intentionally gained access to, used or disclosed CPNI.”
But that definition of breach was crafted eons ago, back when the primary way CPNI was exposed was through “pretexting,” such when the phone company’s employees are tricked into giving away protected customer data.
In January, regulators at the U.S. Federal Communications Commission (FCC) proposed amending the definition of “breach” to include things like inadvertent disclosure — such as when companies expose CPNI data on a poorly-secured server in the cloud. The FCC is accepting public comments on the matter until March 24, 2023.
While it’s true that the leak of CPNI data does not involve sensitive information like Social Security or credit card numbers, one thing AT&T’s breach notice doesn’t mention is that CPNI data — such as balances and payments made — can be abused by fraudsters to make scam emails and text messages more believable when they’re trying to impersonate AT&T and phish AT&T customers.
The other problem with letting companies share or sell your CPNI data is that the wireless carriers can change their privacy policies at any time, and you are assumed to be okay with those changes as long as you keep using their services.
For example, location data from your wireless device is most definitely CPNI, and yet until very recently all of the major carriers sold their customers’ real-time location data to third party data brokers without customer consent.
What was their punishment? In 2020, the FCC proposed fines totaling $208 million against all of the major carriers for selling their customers’ real-time location data. If that sounds like a lot of money, consider that all of the major wireless providers reported tens of billions of dollars in revenue last year (e.g., Verizon’s consumer revenue alone was more than $100 billion last year).
If the United States had federal privacy laws that were at all consumer-friendly and relevant to today’s digital economy, this kind of data collection and sharing would always be opt-in by default. In such a world, the enormously profitable wireless industry would likely be forced to offer clear financial incentives to customers who choose to share this information.
But until that day arrives, understand that the carriers can change their data collection and sharing policies when it suits them. And regardless of whether you actually read any notices about changes to their privacy policies, you will have agreed to those changes as long as you continue using their service.

The U.S. Federal Bureau of Investigation (FBI) this week arrested a New York man on suspicion of running BreachForums, a popular English-language cybercrime forum where some of the world biggest hacked databases routinely show up for sale. The forum’s administrator “Pompompurin” has been a thorn in the side of the FBI for years, and BreachForums is widely considered a reincarnation of RaidForums, a remarkably similar crime forum that the FBI infiltrated and dismantled in 2022.

In an affidavit filed with the District Court for the Southern District of New York, FBI Special Agent John Longmire said that at around 4:30 p.m. on March 15, 2023, he led a team of law enforcement agents that made a probable cause arrest of a Conor Brian Fitzpatrick in Peekskill, NY.
“When I arrested the defendant on March 15, 2023, he stated to me in substance and in part that: a) his name was Conor Brian Fitzpatrick; b) he used the alias ‘pompompurin/’ and c) he was the owner and administrator of ‘BreachForums’ the data breach website referenced in the Complaint,” Longmire wrote.
Pompompurin has been something of a nemesis to the FBI for several years. In November 2021, KrebsOnSecurity broke the news that thousands of fake emails about a cybercrime investigation were blasted out from the FBI’s email systems and Internet addresses.
Pompompurin took credit for that stunt, and said he was able to send the FBI email blast by exploiting a flaw in an FBI portal designed to share information with state and local law enforcement authorities. The FBI later acknowledged that a software misconfiguration allowed someone to send the fake emails.
In December, 2022, KrebsOnSecurity broke the news that hackers active on BreachForums had infiltrated the FBI’s InfraGard program, a vetted FBI program designed to build cyber and physical threat information sharing partnerships with experts in the private sector. The hackers impersonated the CEO of a major financial company, applied for InfraGard membership in the CEO’s name, and were granted admission to the community.
From there, the hackers plundered the InfraGard member database, and proceeded to sell contact information on more than 80,000 InfraGard members in an auction on BreachForums. The FBI responded by disabling the portal for some time, before ultimately forcing all InfraGard members to re-apply for membership.
More recently, BreachForums was the sales forum for data stolen from DC Health Link, a health insurance exchange based in Washington, D.C. that suffered a data breach this month. The sales thread initially said the data included the names, Social Security numbers, dates of birth, health plan and enrollee information and more on 170,000 individuals, although the official notice about the breach says 56,415 people were affected.
In April 2022, U.S. Justice Department seized the servers and domains for RaidForums, an extremely popular English-language cybercrime forum that sold access to more than 10 billion consumer records stolen in some of the world’s largest data breaches since 2015. As part of that operation, the feds also charged the alleged administrator, 21-year-old Diogo Santos Coelho of Portugal, with six criminal counts.
Coelho was arrested in the United Kingdom on Jan. 31, 2022. By that time, the new BreachForums had been live for just under a week, but with a familiar look.
BreachForums remains accessible online, and from reviewing the live chat stream on the site’s home page it appears the forum’s active users are only just becoming aware that their administrator — and the site’s database — is likely now in FBI hands:
Members of BreachForums discuss the arrest of the forum’s alleged owner.
“Wait if they arrested pom then doesn’t the FBI have all of our details we’ve registered with?” asked one worried BreachForums member.
“But we all have good VPNs I guess, right…right guys?” another denizen offered.
“Like pom would most likely do a plea bargain and cooperate with the feds as much as possible,” replied another.
Fitzpatrick could not be immediately reached for comment. The FBI declined to comment for this story.
There is only one page to the criminal complaint against Fitzpatrick (PDF), which charges him with one count of conspiracy to commit access device fraud. The affidavit on his arrest is available here (PDF).

Microsoft on Tuesday released updates to quash at least 74 security bugs in its Windows operating systems and software. Two of those flaws are already being actively attacked, including an especially severe weakness in Microsoft Outlook that can be exploited without any user interaction.
The Outlook vulnerability (CVE-2023-23397) affects all versions of Microsoft Outlook from 2013 to the newest. Microsoft said it has seen evidence that attackers are exploiting this flaw, which can be done without any user interaction by sending a booby-trapped email that triggers automatically when retrieved by the email server — before the email is even viewed in the Preview Pane.
While CVE-2023-23397 is labeled as an “Elevation of Privilege” vulnerability, that label doesn’t accurately reflect its severity, said Kevin Breen, director of cyber threat research at Immersive Labs.
Known as an NTLM relay attack, it allows an attacker to get someone’s NTLM hash [Windows account password] and use it in an attack commonly referred to as “Pass The Hash.”
“The vulnerability effectively lets the attacker authenticate as a trusted individual without having to know the person’s password,” Breen said. “This is on par with an attacker having a valid password with access to an organization’s systems.”
Security firm Rapid7 points out that this bug affects self-hosted versions of Outlook like Microsoft 365 Apps for Enterprise, but Microsoft-hosted online services like Microsoft 365 are not vulnerable.
The other zero-day flaw being actively exploited in the wild — CVE-2023-24880 — is a “Security Feature Bypass” in Windows SmartScreen, part of Microsoft’s slate of endpoint protection tools.
Patch management vendor Action1 notes that the exploit for this bug is low in complexity and requires no special privileges. But it does require some user interaction, and can’t be used to gain access to private information or privileges. However, the flaw can allow other malicious code to run without being detected by SmartScreen reputation checks.
Dustin Childs, head of threat awareness at Trend Micro’s Zero Day Initiative, said CVE-2023-24880 allows attackers to create files that would bypass Mark of the Web (MOTW) defenses.
“Protective measures like SmartScreen and Protected View in Microsoft Office rely on MOTW, so bypassing these makes it easier for threat actors to spread malware via crafted documents and other infected files that would otherwise be stopped by SmartScreen,” Childs said.
Seven other vulnerabilities Microsoft patched this week earned its most-dire “critical” severity label, meaning the updates address security holes that could be exploited to give the attacker full, remote control over a Windows host with little or no interaction from the user.
Also this week, Adobe released eight patches addressing a whopping 105 security holes across a variety of products, including Adobe Photoshop, Cold Fusion, Experience Manager, Dimension, Commerce, Magento, Substance 3D Stager, Cloud Desktop Application, and Illustrator.

Two U.S. men have been charged with hacking into a U.S. Drug Enforcement Agency (DEA) online portal that taps into 16 different federal law enforcement databases. Both are alleged to be part of a larger criminal organization that specializes in using fake emergency data requests from compromised police and government email accounts to publicly threaten and extort their victims.
Prosecutors for the Eastern District of New York today unsealed criminal complaints against Sagar Steven Singh — a.k.a “Weep” — a 19-year-old from Pawtucket, Rhode Island; and Nicholas Ceraolo, 25, of Queens, NY, who allegedly went by the handles “Convict” and “Ominus.”
The Justice Department says Singh and Ceraolo belong to a group of cybercriminals known to its members as “ViLE,” who specialize in obtaining personal information about third-party victims, which they then use to harass, threaten or extort the victims, a practice known as “doxing.”
“ViLE is collaborative, and the members routinely share tactics and illicitly obtained information with each other,” prosecutors charged.
The government alleges the defendants and other members of ViLE use various methods to obtain victims’ personal information, including:
-tricking customer service employees;
-submitting fraudulent legal process to social media companies to elicit users’ registration information;
-co-opting and corrupting corporate insiders;
-searching public and private online databases;
-accessing a nonpublic United States government database without authorization
-unlawfully using official email accounts belonging to other countries.
The complaint says once they obtained a victim’s information, Singh and Ceraolo would post the information in an online forum. The government refers to this community only as “Forum-1,” saying that it is administered by the leader of ViLE (referenced in the complaint as “CC-1”).
“Victims are extorted into paying CC-1 to have their information removed from Forum-1,” prosecutors allege. “Singh also uses the threat of revealing personal information to extort victims into giving him access to their social media accounts, which Singh then resells.”
Sources tell KrebsOnSecurity in addition to being members of ViLE, both Weep and Ominous are or were staff members for Doxbin, a highly toxic online community that provides a forum for digging up personal information on people and posting it publicly. This is supported by the Doxbin administrator’s claimed responsibility for a high-profile intrusion at the DEA’s law enforcement data sharing portal last year.
A screenshot of alleged access to the Drug Enforcement Agency’s intelligence sharing portal, shared by “KT,” the current administrator of the doxing and harassment community Doxbin.
The government alleges that on May 7, 2022, Singh used stolen credentials to log into a U.S. federal government portal without authorization. The complaint doesn’t specify which agency portal was hacked, but it does state that the portal included access to law enforcement databases that track narcotics seizures in the United States.
On May 12, 2022, KrebsOnSecurity broke the news that hackers had gained access to a DEA portal that taps into 16 different federal law enforcement databases. As reported at the time, the inside scoop on how that hack went down came from KT, the current administrator of the Doxbin and the individual referenced in the government’s complaint as “CC-1.”
Indeed, a screenshot of the ViLE group website includes the group’s official roster, which lists KT at the top, followed by Weep and Ominus.

In March 2022, KrebsOnSecurity warned that multiple cybercrime groups were finding success with fraudulent Emergency Data Requests (EDRs), wherein the hackers use compromised police and government email accounts to file warrantless data requests with social media firms and mobile telephony providers, attesting that the information being requested can’t wait for a warrant because it relates to an urgent matter of life and death.
That story showed that the previous owner of the Doxbin also was part of a teenage hacking group that specialized in offering fake EDRs as a service on the dark web.
Prosecutors say they tied Singh to the government portal hack because he connected to it from an Internet address that he’d previously used to access a social media account registered in his name. When they raided Singh’s residence on Sept. 8, 2022 and seized his devices, investigators with Homeland Security found a cellular phone and laptop that allegedly “contained extensive evidence of access to the Portal.”
The complaint alleges that between February 2022 and May 2022, Ceraolo used an official email account belonging to a Bangladeshi police official to pose as a police officer in communication with U.S.-based social media platforms.
“In these communications, Ceraolo requested personal information about users of these platforms, under the false pretense that the users were committing crimes or in life-threatening danger,” the complaint states.
For example, on or about March 13, 2022, Ceraolo allegedly used the Bangladeshi police email account to falsely claim that the target of the EDR had sent bomb threats, distributed child pornography and threatened officials of the Bangladeshi government.
On or about May 9, 2022, the government says, Singh sent a friend screenshots of text messages between himself and someone he had doxed on the Doxbin and was trying to extort for their Instagram handle. The data included the victim’s Social Security number, driver’s license number, cellphone number, and home address.
“Look familiar?” Singh allegedly wrote to the victim. “You’re gonna comply to me if you don’t want anything negative to happen to your parents. . . I have every detail involving your parents . . . allowing me to do whatever I desire to them in malicious ways.”
Neither of the defendants could be immediately reached for comment. KT, the current administrator of Doxbin, declined a request for comment on the charges.
Ceraolo is a self-described security researcher who has been credited in many news stories over the years with discovering security vulnerabilities at AT&T, T-Mobile, Comcast and Cox Communications.
Ceraolo’s stated partner in most of these discoveries — a 30-year-old Connecticut man named Ryan “Phobia” Stevenson — was charged in 2019 with being part of a group that stole millions of dollars worth of cryptocurrencies via SIM-swapping, a crime that involves tricking a mobile provider into routing a target’s calls and text messages to another device.
In 2018, KrebsOnSecurity detailed how Stevenson earned bug bounty rewards and public recognition from top telecom companies for finding and reporting security holes in their websites, all the while secretly peddling those same vulnerabilities to cybercriminals.
According to the Justice Department, if convicted Ceraolo faces up to 20 years’ imprisonment for conspiracy to commit wire fraud; both Ceraolo and Singh face five years’ imprisonment for conspiracy to commit computer intrusions.
A copy of the complaint against Ceraolo and Singh is here (PDF).
